Reading that it was more of an issue with his skating. I have only seen highlights, is it really that bad?

I will slightly disagree with rt.

His skating at the summer camp much like earlier this WHL season was an issue. Based on those snapshots the belief is he would be exposed on larger ice. That being said I've noticed improvement in Samuelsson's stride which would cause me to believe it would be less of an issue today. Coupled with the strength of his recent play (10 game point streak), solid all around defensive game, and strong physical play Samuellson should be on this team.

Bottom line is Team USA was looking for a reason not to bring him and they found it in his skating. Next year they won't have a reason.
